Background Art

The contents described in this section merely provide backgroundinformation on the present exemplary embodiment but do not constitutethe related art.

Recently, as the use of mobile devices such as smart phones and tableshas increased and TVs and monitors employing a flat panel display (FPD)have been widely distributed, the mobile devices or displays such as aFPD are being used in daily life.

SUMMARY

Users maintain an undesirable posture while using mobile devices for along time and perform the work with a monitor which is installed on adesk so that the users perform the work with an undesirable posture fora long time. When the user lives in the wrong posture for a long time,problems such as discs may occur in the cervical vertebrae in the neck.Further, a disease such as a text neck syndrome that the cervicalvertebrae in the neck does not maintain the normal shape, but isdeformed in an abnormal shape may occur.

When a task is performed using a monitor, the position of the monitor isfixed so that if the user concentrates on the task, it is not easy toperform the task with an ideal posture. Further, it is not easy toconsistently visit the hospital or exercise during the busy daily life.Even though a correction tool is used, it is only a one-time thing sothat there is a limit to solving the fundamental problem.

Further, even though a position where the monitor or the TV is mountedis changed by a monitor or a TV stand, the monitor or the TV is fixed toone position so that it cannot fundamentally prevent an unconsciousabnormal change of the posture of the user during the use.

Therefore, when the mobile devices are used for a long time, theimbalance of the posture is caused, so that a normal curve of thecervical vertebrae is lost, and a load which is three to four timeshigher than usual is transmitted to the neck, which cause the nervedamage, and head, neck, waist, and shoulder pains to cause poorconcentration and chronic fatigue.

FIGS. 2 to 7 are views specifically illustrating components of a displaymounting device for posture correction according to an exemplaryembodiment of the present invention.

FIG. 2 is a view illustrating entire components of a display mountingdevice for posture correction according to an exemplary embodiment ofthe present invention and FIG. 3 is a view illustrating main componentsof a display mounting device for posture correction according to anexemplary embodiment of the present invention.

The display mounting device 10 for posture correction includes a displaymount 100, a driving motor 200, an arm unit 300, and a tilting unit 400.The display mounting device 10 for posture correction may omit somecomponents among various components which are exemplarily illustrated inFIG. 2 or may further include other component.

The display mount 100, the driving motor 200, the arm unit 300, and thetilting unit 400 are provided in a mount housing 500. Here, the mounthousing 500 is a component which forms an outer appearance of thedisplay mounting device 10 for posture correction.

The display mount 100 may install and fix the display 20 to mount thedisplay 20 to be used by the user.

The driving motor 200 may provide a driving force tohorizontally/vertically move the display 20 equipped in the displaymount 10 and adjust a tilting angle.

The driving motor 200 may provide a driving force required to linearlymove the display 20 in a predetermined direction and adjust the tiltingangle of the display 20.

An output to smoothly drive the driving motor 200 is determinedaccording to a weight of the display 20 to be equipped so that thedisplay mounting device 10 for posture correction determines a maximumweight of the display 20 to be equipped in advance and selects a drivingmotor 200 having an appropriate output according to the weight.

Further, the driving motor 200 is roughly divided into a DC motor and anAC motor and there are various driving motors according to a durabilityand a driving precision so that it is desirable to select an appropriatemotor in accordance with the environment in which the display mountingdevice 10 for posture correction is used. However, when it is consideredthat a driving device for the display mounting device of the presentdisclosure is used for the display mounting device 10 which is installedon a TV stand and a size of the display mounting device 10 is not large,it is desirable to select a driving motor 200 which is not large andalso desirable to select a driving motor 200 which has a low noiserather than the large driving force.

In the display mounting device 10 for posture correction, the linearmotion such as horizontal/vertical movement and a rotational motion suchas tilting angle adjustment need to be simultaneously performed by onedriving motor 200. Further, the driving motor 200 is a heavier componentamong the components of the display mounting device 10 so that in orderto stably operate the display mounting device 10, the driving motor 200may be provided below the display mounting device 10 to be adjacent tothe fixing mount 600 which fixes the mounting device.

The arm unit 300 converts the rotational driving force of the drivingmotor 200 into a linear driving force to move the equipped display 20 ina predetermined direction, that is, a direction in which the horizontalmovement and the vertical movement are simultaneously performed.

The arm unit 300 converts the rotational motion generated from thedriving motor 200 into a linear motion. A configuration which convertsthe linear motion into the rotational motion is roughly divided into aball screw and a lead screw. The ball screw is precisely and smoothlydriven, but is expensive and the lead screw has a less durability but ischeap so that the screws may be selected according to the environmentand the purpose that the display mounting device 10 is used.

It may be more effective for the display mounting device 10 to use alead screw 330 having a relatively low noise, a low price, and arelatively simple configuration, but is not necessarily limited thereto.

It is effective that the display mounting device 10 performs the linearmovement and adjust the tilting angle by one driving motor 200 and thedisplay 20 not only horizontally moves, but also vertically moves sothat in order to efficiently perform vertical motion and horizontalmotion at one time, the linear motion is desirably performed by beingtilted at a predetermined angle.

Accordingly, the arm unit 300 of the present invention connects thesecond driving assembly 310, the first driving assembly 320, and thelead screw 330 which transmit the rotational driving force to thedriving motor 200 provided therebelow to provide the driving force.

The tilting unit 400 interworks with the arm unit 300 and adjusts thetilting angle of the display 20 according to the linear motion of thearm unit 300.

According to the exemplary embodiment of the present invention, thetilting unit 400 includes a tilting wheel 410 and a tilting shaft 420.The tilting unit 400 may omit some components among various componentswhich are exemplarily illustrated in FIG. 2 or may further include othercomponent.

The tilting wheel 410 rotates by being engaged with the first link gear332 of the lead screw 330 and is implemented by a worm wheel.

The tilting shaft 420 is coupled to pass through a center of the tiltingwheel 410 and is connected to the display mount 10 to tilt the displaymount 100 while rotating together by the rotation of the tilting wheel410. Specifically, the tilting shaft 420 forms a protrusion on a sidesurface to be slidably coupled to a groove formed on the display mount100 to be fixed.

The tilting unit 400 adjusts the tilting angle of the display 20 incoordination with the linear motion of the arm unit 300. When thedisplay 20 moves toward the user and is maintained in a vertical state,a posture that looks at the display 20 is not normal as well asinconvenient to use so that it is necessary to appropriately maintain auser's viewing angle for the display 20 by tilting an upper portion ofthe display 20 toward the user while moving the display 20 toward theuser. To this end, it is necessary to adjust the tilting angle of thedisplay 20 in coordination with the linear motion by the arm unit 300and the tilting angle may be adjusted by the tilting unit 400.

In order to adjust the tilting angle using one driving motor 200, oneend of the second driving assembly 310 is coupled to the driving motor200 and the other end is connected to the first driving assembly 320 andthe length of the arm unit 300 may be stretched or extended whilerotating the lead screw 330 by the second driving assembly 310 and thefirst driving assembly 320. Here, the lead screw 330 rotates to rotatethe worm wheel of the tilting unit 400 to tilt the display 20. That is,the lead screw 330 and the tilting unit 400 interwork to convert thelinear motion into the rotational motion, which is used to adjust thetilting angle by means of the worm wheel in the tilting unit 400.

Referring to FIG. 2 , the mount housing 500 is a component which formsan outer appearance of the display mounting device 10 for posturecorrection. The mount housing 500 is formed to have a cylindrical shapeto provide a design element and increase a storage efficiency of thecomponents accommodated therein, such as the driving motor 200, the armunit 300, and the tilting unit 400 and reduce the entire device size.However, the outer appearance of the display mounting device 10 is notnecessarily limited thereto.

Here, the driving motor 200 and the second driving assembly 310 of thearm unit 300 may be fixed to the fourth column parts 540 a and 540 b.

The second column parts 520 a and 520 b are assembled on the upper endsof the first column parts 510 a and 510 b and the third column parts 530a and 530 b are assembled on the upper ends of the second column parts520 a and 520 b. Here, when the arm unit 300 is stretched, the secondcolumn parts 520 a and 520 b are stretched along the first column parts510 a and 510 b and the third column parts 530 a and 530 b are stretchedalong the second column parts 520 a and 520 b. By doing this, thedisplay mounting device 10 for posture correction may be extended orcontracted in three stages, but is not necessarily limited thereto andmay be extended or contracted in a plurality of stages by changing astructure of the gear provided in the arm unit 300 and a structure ofthe mount housing.

A fixing mount 600 may fix the display mounting device 10 to a desk or aTV stand to be installed. The fixing mount 600 may be implemented by anycomponent which fixes the display mounting device 10 and may be providedas a clamp to stably install the display 20 in consideration of theweight of the display 20, but is not necessarily limited thereto.

The fixing mount 600 may be fixed to be connected to the driving motor200 and provided in the first column parts 510 a and 510 b.

According to the exemplary embodiment of the present invention, aposition detecting unit 30 and a control unit 32 may be located in thefixing mount 600, but it is not necessarily limited thereto.

According to the exemplary embodiment of the present invention, as longas the fixing mount fixes the display mounting device 10, the shape ofthe fixing mount 600 is not specifically limited, and the fixing mountmay be provided as a clamp to stably install the display 20 inconsideration of the weight of the display 20, but is not necessarilylimited thereto.

Further, the environment that the display mounting device 10 isinstalled may vary so that an extension block (not illustrated) whichextends the driving device in a vertical direction and a horizontaldirection may be further installed. The extension block may bemanufactured to have the same shape as the mount housing 500 to extendthe driving device in a vertical direction and may be manufactured tohave a planar shape to extend the driving device in a horizontaldirection, but is not necessarily limited thereto. Specifically, theextension block has a predetermined length and a predetermined height toadjust a height and a depth of the display mounting device 10 and may belocated between the driving motor 200 and the fixing mount 600. Forexample, the extension block is located in a horizontal direction toform the driving motor 200 and the arm unit 300 to be formed in front ofor behind the position fixed by the fixing mount 600.

The second driving assembly 310 includes a rotary gear 312, a secondlink gear 314, a rotary shaft 318, a second link shaft 317, and a secondhousing 319. The second driving assembly 310 may omit some componentsamong various components which are exemplarily illustrated in FIG. 4 ormay further include other component.

The rotary gear 312 is located to be in contact with the driving gear210 of the driving motor 200 and receives a power generated by thedriving motor 200. Here, the rotary gear 312 forms protrusions with thesame interval as the driving gear 210 to be engaged and rotate totransmit the power without causing the energy loss.

The rotary gear 312 may be fixed to the second housing 319.

According to the exemplary embodiment of the present invention, therotary gear 312 is coupled to one surface of the second housing 319 andcoupled by forming grooves therein. For example, the rotary gear 312forms a hexagonal shape therein and forms grooves on two facing surfacesto be coupled and fixed to the second housing 319. Here, an inner shapeof the rotary gear 312 is not necessarily limited to the hexagonal shapeand may be formed to have the same shape as the shape of an outersurface of the rotary shaft 318.

Here,the second link gear 314 forms protrusions having the same interval asthe first link gear 322 to be engaged and rotate to transmit the powerto the first link gear 322 without causing the energy loss.

According to the exemplary embodiment of the present invention, eventhough it is illustrated that the second link gear 314 forms a hexagonalshape therein, it is not necessarily limited thereto and may beassembled by forming the same shape as the shape of the outercircumferential surface of the rotary shaft 318.

The rotary shaft 318 forms a hexagonal shape. Here, even though it isillustrated that the rotary shaft 318 forms a hexagonal shape, it is notlimited thereto and may form a polygonal shape.

According to the exemplary embodiment of the present invention, when therotary shaft 318 is formed in a circle, the rotary shaft may not rotateas the second housing 319 coupled to the rotary shaft 318 rotates.Accordingly, the rotary shaft 318 is formed to have a polygonal shape tobe coupled to the second housing 319 to rotate together as the secondhousing 319 rotates.

The rotary shaft 318 forms grooves on two opposing surfaces.

FIG. 11 includes diagrams showing a display mount and a mounting jig ofa display mounting device for posture correction according to anexemplary embodiment of the present invention.

(a) of FIG. 11 is a view illustrating a mounting jig, (b) of FIG. 11 isa view illustrating a display mount, and (c) of FIG. 11 is a viewillustrating the coupling of the mounting jig and the display mount.

The display mount 100 may fix the display 20 to mount the display 20.

The mounting jig 110 may be fastened to the display 20 and the displaymount 100 to connect the display 20 and the display mount 100.

The display mount 100 of the present invention is a configuration whichprovides and fixes the display 20 including a monitor, a TV, and amobile device to be used by the user. Even though a stand which fixesthe display 20 to a predetermined position is attached to the display20, a fixing unit is generally provided on a rear surface of the display20 to fix the display 20 to the mounting device. The display mount 100installs and fixes the display 20 by means of the fixing unit providedon the rear surface of the display 20. The fixing unit is generallyprovided in the standard called VESA and the display mount 100 isdesirably manufactured in accordance with the VESA standard. Accordingto the VESA standard, generally, a bolt groove having a predeterminedshape is provided to closely attach and fix the rear fixing unit withthe bolt. During the fixing with the bold, the display 20 needs to beheld, so that the fastening process is not easy.

Accordingly, the display mount 100 of the present invention may use themounting jig 110 to be coupled to the rear surface of the display 20 andthe display mount 100 to install the display 20 by one touch. Forexample, after installing one side of the mounting jig 110 in thedisplay 20 and installing the other side in the display mount 100, themounting and fixing can be made just by lifting the display 20 to befitted into the display mount 100.

According to the exemplary embodiment of the present invention, aportion of the mounting jig 110 which is coupled to the display mount100 protrudes to form grooves on both sides and the mounting jig may beslidably coupled to the display mount 100 along the grooves formed onboth sides of the protruding portion, but is not necessarily limitedthereto.

FIGS. 12 and 13 are views specifically illustrating stretching andextension of a display mounting device for posture correction accordingto an exemplary embodiment of the present invention.

FIG. 12 is a view illustrating rotation of gear to stretch and extend adisplay mounting device for posture correction according to theexemplary embodiment of the present invention and FIG. 13 is a viewillustrating an extended arm unit of a display mounting device forposture correction according to an exemplary embodiment of the presentinvention.

In the display mounting device 10 for posture correction, when the gear200 operates, the arm unit 300 may be stretched or extended as thedriving gear 210 formed in the gear 200 rotates. For example, in thedisplay driving device 10 for posture correction, when the driving gear210 rotates to the left, the rotary gear 312 engaged with the drivinggear 210 may rotate to the right. When the rotary gear 312 rotates tothe right, the second link gear 314 rotates to the right while therotary shaft 318 rotates to the right by the second housing 319connected to the rotary gear 312. When the second link gear 314 rotatesto the right, the first link gear 322 engaged with the second link gear314 rotates to the left. The arm unit 300 may be extended by theabove-described process and thus the lead screw 330 may rotate. At thistime, the lead screw 330 rotates to the left and the tilting unit 400connected perpendicularly to the lead screw 330 rotate to the right sothat an angle of the display mount 100 may be reduced. Here, when theangle of the display mount 100 is reduced, it means that the displaymount 100 moves to be directed to the lower end.

The arm unit 300 of the display mounting device 10 for posturecorrection is extended and the angle of the display mount 100 isadjusted by the above-described process. The extended arm unit 300 mayreturn to its original state and the angle of the display mount 100 mayalso return to its original state as the driving gear 210 rotates in anopposite direction.

The above-described process is an example for explaining the presentinvention so that it is not necessarily limited to those described aboveand may be implemented to the contrary or a position of each gear ischanged to stretch the arm unit 300 or change the angle of the displaymount 100.

The arm unit 300 is a configuration which moves the display 20 tocorrect the posture of the user or adjust the position of the display 20to be customized according to the usage environment of the display 20.The position of the display 20 is divided into a vertical position onthe desk and a horizontal position to the user and the vertical andhorizontal positions can be adjusted in the terms of the distancebetween the user and the display 20. However, in terms of the posturecorrection of the user, the head of the user needs to be moved so thatthe tinting angle of the display 20 needs to be adjusted in addition tothe movement in terms of the distance.

It is desirable to obliquely move the display 20 toward the face of theuser rather than a movement trajectory of the display 20 which movesvertically or horizontally, separately or sequentially. In other words,in order to move the head of the user to improve the text neck disease,when an upper end of the display 20 is inclined toward the user whileincreasing a vertical distance of the display 20 from the desk andreducing a horizontal distance with the user, the head is tilted back sothat the posture of the user may be correctly corrected.

Accordingly, the display mounting device 10 may adjust the tilting angleof the display 20 using the tilting unit 400 at one time whilestretching or contracting the length using the arm unit 300 by combiningthe arm unit 300 and the tilting unit 400. When a driving for each ofthe components is provided, a degree of freedom of the movementtrajectory of the display 20 can be increased, but it may bedisadvantageous because the control is complex and the manufacturingcost is increased.

According to the exemplary embodiment of the present invention, thedisplay mounting device 10 may be configured not only to move thedisplay 20 toward the user, but also tilt the display to the left andright using the arm unit 300 and the tilting unit 400.

Referring to FIG. 13 , the driving motor 200 is fixed to the fourthcolumn parts 540 a and 540 b provided in the first column parts 510 aand 510 b and the second driving assembly 310 of the arm unit 300 may befixed thereto.

In the first column parts 510 a and 510 b, the first housing 326 of thefirst driving assembly 320 and the second housing 319 of the seconddriving assembly 310 may be located.

In the second column parts 520 a and 520 b, the arm assembling unit 340is located and the first arm guide 341 and the second arm guide 345which enclose the first link gear 322 and the first link shaft 325 fixedto the arm assembling unit 340 may be located.

In the third column parts 530 a and 530 b, the first link shaft 325 ofthe first driving assembly 320 and the lead screw 330 may be located.

FIGS. 14 and 15 are views illustrating a display mounting control systemusing a display mounting device for posture correction according to anexemplary embodiment of the present invention.

FIG. 14 is a view illustrating a display mounting control system using adisplay mounting device for posture correction according to an exemplaryembodiment of the present invention and FIG. 15 is a view illustratingan extended arm unit and a tilted display mount of a display mountingdevice for posture correction according to an exemplary embodiment ofthe present invention.

The display mounting control system 40 includes a display mountingdevice 10, a position detecting unit 30, and a control unit 32. Thedisplay mounting control system 40 may omit some components amongvarious components which are exemplarily illustrated in FIGS. 14 and 15or may additionally include other component.

In the display mounting control system 40, the display mounting device10 is equipped in the display mount 100 to which the display 20 to beused by the user is equipped and fixed and the position of the user isdetected by the position detecting unit 30 with respect to the equippeddisplay 20. In the display mounting control system 40, the posture ofthe user, such as a bending angle of the neck of the user, may bedetermined on the basis of the detected position and the display 20 ismoved in a direction in which a horizontal distance and a verticaldistance of the display 20 are simultaneously adjusted by the displaymounting device 10 to correct the posture of the user determined by thecontrol unit 32, and the tilting angle of the display 20 is adjustedwithin a predetermined range in association therewith.

The position of the user indicates a position according to a distancebetween the user and the position detecting unit 30 with respect to thedisplay 20 and may be provided separately for the head, the neck, andthe body.

The position detecting unit 30 may detect the position of the user withrespect to the display 20 mounted on the display mount 100 to determinethe posture of the user.

The display mounting device 10 adjusts the position of the display 20 inaccordance with the environment in which the user uses the display 20and moves the display 20 to correct the posture of the user.

The control unit 32 controls an overall operation of the displaymounting device 10 to determine the posture of the user on the basis ofthe user position detected by the position detecting unit and controlthe display mounting device 10 to adjust the movement of the display 20,thereby correcting the posture of the user.

According to the exemplary embodiment of the present invention, thedisplay mounting control system 40 determines a first regioncorresponding to a face of the user, a second region corresponding to achest, and a third region corresponding to the neck from a plurality ofdistance information of the image acquired by an LED proximity sensorand an IR distance sensor of the position detecting unit 30 and thecontrol unit 32 diagnoses the posture of the user to drive the drivingmotor or issue an alarm to the user in consideration of distribution offeature values belonging to each region.

The display mounting control system 40 may distinguish the first region,the second region, and the third region by the image processing, for theabove-described purpose. For example, it is confirmed that the postureis changed to a posture that the head is leaned forward for 10 minutesby checking that a first region distance value of 50 cm, a second regiondistance value of 53 cm, and a third region distance value of 52 cm atthe time of 13:00 are changed to the first region distance value of 48cm, the second region distance value of 52 cm, and the third regiondistance value of 51 cm at the time of 13:10.

The display mounting control system 40 recognizes the posture of theuser and determines the posture to adaptively control the user.Specifically, the display mounting control system 40 utilizes a singleposture recognizing sensor or a plurality of posture recognizing sensorsin the position detecting unit 30 to measure the posture in front of theuser. Here, the posture recognizing sensor may be implemented by adistance sensor and also implemented by a sensor using the infrared rayor laser. For example, the posture recognizing sensor may be implementedby a 3D time of flight (TOF) sensor, but is not necessarily limitedthereto.

According to the exemplary embodiment of the present invention, when theposition detecting unit 30 uses a single sensor, the display mountingcontrol system 40 may measure a distance from the posture recognizingsensor to the user's head to measure the posture of the user. When theposition detecting unit 30 uses a plurality of sensors, the posture ofthe user may be measured by measuring a distance from the posturerecognizing sensor to the torso of the user.

Referring to FIGS. 14 and 15 , even though it is illustrated that theposition detecting unit 30 of the display mounting control system 40uses a plurality of posture recognizing sensors, it is not necessarilylimited thereto.

The display mounting control system 40 records the posture determined bythe position detecting unit 30 in the chronological order through thecontrol unit 32. At this time, the determined posture allows todetermine that the seat is empty, the head is gradually tilted forward,and the user feels uncomfortable due to the posture guiding, but is notnecessarily limited thereto.

Further, the control unit 32 may optimize the movement distance and thespeed of the display 20 for the user, in accordance with thedetermination. For example, from a long-term point of view, the movementdistance and the speed of the display 20 may be optimized for the user.The long-term view may be set to 12 weeks or longer because a generalmusculoskeletal rehabilitation training takes 12 weeks, but is notnecessarily limited thereto.

The position detecting unit 30 may detect the position of the user whouses the display with respect to the display.

Referring to FIGS. 14 and 15 , the position detecting unit 30 may belocated at a lower end of the display mounting device for posturecorrection, but is not necessarily limited thereto and may be located ina position that the distance from the user can be measured.

The position detecting unit 30 may utilize at least one posturerecognizing sensor to measure the posture in front of the user bydividing the posture into at least one region. Here, the posturerecognizing sensor may measure a distance to a face position of theuser.

The position detecting unit 30 may divide the region into a first regionindicating a position of a user's face, a second region indicating aposition of the user's torso, and a third region indicating a positionof the user's neck to determine the distance from the user through atleast one posture recognizing sensor. The position detecting unit 30generates distance information from the user from the first region, thesecond region, and the third region to transmit the distance informationto the control unit 32.

The control unit 32 determines the posture of the user on the basis ofthe position of the user detected by the position detecting unit 30 andcontrols the display mounting device 10 to correct the posture of theuser.

The control unit 32 records the position of the user detected by theposition detecting unit 30 at every time to determine the state of theuser and distinguishes at least one region to diagnose the posture ofthe user in consideration of the distribution of the feature valuesbelonging to each region according to the state of the user at everytime to calculate an adjustment value to adjust the display mountingdevice 10.

According to the exemplary embodiment of the present invention, theadjustment value may include a speed at which the driving motor 200 isdriven, a left or right driving direction to drive the driving gear 210,and a time when the driving motor 20 is driven, but is not necessarilylimited thereto.

The control unit 32 may drive the driving motor 200 using the adjustmentvalue calculated by a predetermined reference according to the postureof the user to control the position of the display.

The control unit 32 adjusts the movement distance and the speed of thedisplay by the adjustment value and stores the movement distance and thespeed of the display 20 according to the adjustment value to predict andprovide a posture habit change of the user and a disease according tothe posture habit. Here, the movement distance and the speed of thedisplay may be determined by adjusting the movement distance and themoving speed of the arm unit 300 of the display mounting device 10.

The control unit 32 may vary the speed according to the movementdistance. For example, the control unit 32 adjusts the display mountingdevice 10 at a high speed in a predetermined zone and at a slow speed inthe other zone and also adjust the display mounting device for everyuser or every posture at a variable speed.

The display mounting control system 40 collects the user's positiondetected by the position detecting unit 30 in real-time and includes anotification unit (not illustrated) for notifying the user when thedistance between the user and the display 20 is deviated from apredetermined range.

The position detecting unit 30 may detect the position of the user withrespect to the display 20. The position of the user is used to determinethe posture of the user by the control unit 32 so that it is desirableto detect various positions in a plurality of points or portions of theuser, rather than simply detecting only one point of the user, withrespect to the display 20. In order to detect the position of the user,various sensors may be utilized, such as a sensor using infrared ray orlaser or a time of flight (TOF) sensor. It is necessary to detect theposition from a plurality of portions of the user, so that a sensorwhich detects various positions at one time such as a TOF sensor isdesirable rather than a sensor which detects a single position.Specifically, it is important to identify whether the posture of theuser is a text neck so that it is important to essentially identify thepositions of the face, the neck, and the torso of the user.

Even though an example that the position detecting unit 30 which detectsthe position of the user is installed on a front lower end of thedisplay mounting device 10 has been illustrated, the detecting unit maybe provided as an attached type to be provided on a lower end or anupper end of the display 20. However, regardless of the installationposition, in order to accurately measure the position of the user, abasic setting and a correcting process may be desirably performed.

According to the exemplary embodiment of the present invention, aplurality of position detecting units 30 is provided to measure thedistances to the user's head, neck, and torso for every region or atleast one position detecting unit is provided to move up and down andleft and right to measure the distance from the head to the torso of theuser, but is not necessarily limited to those described above.

The display mounting device 10 desirably moves within a predeterminedrange because the display 20 has its own weight and the movement beyondthe predetermined range has no meaning. It is not possible to set thehorizontal distance, the vertical distance, and the tilting angle thatthe display mounting device 10 moves the display 20 to infinite, so thatit is desirable to restrict the movement within a predetermined range.In the case of the horizontal distance, since the display mountingdevice 10 is generally installed on the end of the desk, it isreasonable to determine the horizontal distance with respect to thevertical length of the desk and the size and the viewing angle of thedisplay.

According to the exemplary embodiment of the present invention, inconsideration of the color and the letter recognition, the viewing anglemay be set to 35 degrees to the left and right. In consideration of theweight of the display, the posture of the user, and the limitation ofadjusting the tilting angle, the maximum tilting angle may be set to 30degrees. Even though the vertical distance is related to the user'sseating height, the height of the display mounting device of the presentinvention can be relatively freely adjusted so that the range of thevertical distance may be derived by the limit of the tilting angle. Therange of the horizontal distance can be set to 0 to (D−S/2 tan 35) bycomprehensively considering the above-description. Of course, theviewing angle can be adjusted in consideration of the characteristic ofthe user's eyesight. A limit of the tilting angle is 30 degrees so thatthe vertical distance may be set to 0 to (S*sin 30)/(2 tan 35). That is,the range (W1) of the horizontal movement distance is adjusted to0˜(D—S/2 tan 35), the range (W2) of the vertical movement distance isadjusted to 0˜(S*sin 30)/(2 tan 35), and the tilting angle (t3) isadjusted to 0 degree to 30 degrees.

The display mounting device 10 is configured not only to move thedisplay toward the user, but also to tilt the display to the left andright, but it is desirable to determine whether to add the displaymounting device 10 in terms of the usefulness based on the manufacturingcost and the easiness of the control.

The control unit 32 is a configuration which controls the displaymounting device 10 to correct the posture of the user. The control unit32 determines the posture of the user using the position of the userdetected by the user position detecting unit 30. For example, thecontrol unit 32 detects a first region indicating a distance from auser's face, a second region indicating a distance from the user's neck,and a third region indicating a distance from the user's torso andextracts an angle a2 to determine the posture of the user, that is,whether the posture is a text beck, after connecting the positions.

The angle a2 is extracted from the position of the user so that theangle a2 is smaller than a normal angle a1 so that a process ofcalculating a correction value by several tests is essential todetermine an accurate posture. Further, when a specific position isdetected, a position of the face, the neck, and the torso which is aposition of the user necessary to determine the posture of the user isestimated from the position to be used. The calibration through the testis essential.

The control unit 32 sets a movement trajectory and a movement cycle ofthe display 20 in advance to automatically control the display 20. Forexample, if the display 20 is controlled to move back and forth with apredetermined cycle to relax or strengthen the muscles around the neck,the user may unconsciously move the head back and forth or nod up anddown during the working so that the muscles around the neck may berelaxed or strengthened without awareness. According to the presentinvention, even though a correcting mode for correcting the posture ofthe user and a training mode for relaxing or strengthening the musclesaround the neck are exemplified, user customized modes may be designedby varying the movement trajectory and the cycle or a separate mode maybe newly created.

The display mounting device 10 may further include a notification unitwhich is installed in a noticeable position by the user such as a frontportion of the display mounting device 10 to provide several events ornotification generated from the display mounting device 10 to the user.

According to the exemplary embodiment of the present invention, thenotification unit may be provided as an LCD panel having an appropriatesize to transmit the notification for a mode which is being driven or aposture of the user as an image or a text or also transmit a simplenotification such as whether the power is on/off or whether the postureof the user is appropriate, as a color or a number of turned on LEDs,using a plurality of LEDs.

The display mounting device 10 may further include a wireless modulewhich transmits various information of the display mounting device 10 toa terminal registered by the user, such as a smart phone or a tablet ortransmits and controls contents controlled by the user, such as positionadjustment of the display 20, setting of the movement trajectory, cyclesetting, or setting of the training mode or the correcting mode to thedisplay mounting device through the user's terminal, using anapplication of a predetermined UI.

According to the exemplary embodiment of the present invention, thedisplay mounting control system 40 determines the posture of the user onthe basis of the positions of the face, the neck, and the torso, andfurther determines the posture on the basis of the position that theface, the neck, and the torso are deviated from the display 20 to theleft or right. Specifically, the position detecting unit 30 may measuredistances of the face, the neck, and the torso which are deviated fromthe center of the display 20 to the left or right and determines aposture that is tilted sideways or a posture that the head is tiltedaccording to the deviated distance. Therefore, the display mountingcontrol system 40 may determine all the up, down, left, and rightpostures of the user and move the display 20 with respect to thepostures. Further, the display mounting control system 40 assigns aweight to the distances from the face, the neck, and the torso and thedistances of the face, the neck, and the torso which are deviated fromthe center of the display 20 acquired by the position detecting unit 30to set a degree of moving the display mounting device 10. Here, theweight may be set on the basis of the correction portion according tothe health condition of the user and a portion that the distancedeviated from the optimal state is large and a portion considered tomaintain a correct portion may be differently set according to a currentcondition of the user to be used to train the posture and the posturemay be corrected for each portion of the user.

The control unit 32 may record the posture determined by the positiondetecting unit 30 in a chronological order. At this time, the determinedposture allows to determine that the seat is empty, the head isgradually tilted forward, and the user feels uncomfortable due to theposture guiding, but is not necessarily limited thereto.

According to another exemplary embodiment of the present invention, thecontrol unit or a processor of the present exemplary embodiment maycalculate a posture index indicating whether the posture of the user iscorrect using relational factors such as the distance from each point(face, neck, and torso) of the user and a current position (height orangle) of the monitor. Further, the posture index may be calculated byfurther considering the previously input setting value, that is, a userprofile, such as the age, the gender, and the height of the user. Forexample, a distance relational value which is optimized by varioussimulations performed for the relational factors is calculated as areference value and the posture index may be calculated by an error fromthe actual measurement value.

FIG. 16 is a view illustrating a state diagram of a display mountingcontrol system of a display mounting device for posture correctionaccording to an exemplary embodiment of the present invention.

The state diagram 1500 includes an unknown stage 1510, a user existstage 1520, a bad posture stage 1530, a move-to-up stage 1540, andmove-to-home stage 1550.

The unknown stage 1510 is a state in which the position of the user isnot known so that the position detecting unit 30 of the display mountingcontrol system 40 may indicate a state in which the user is not locatedwithin a measurement distance.

The user exist stage 1520 is a state in which the user exists so thatthe position detecting unit 30 of the display mounting control system 40may indicate a state in which the user is located within a measurementdistance.

The bad posture stage 1530 indicates that a state in which the postureof the user is bad and the user may indicate a state that the user islocated with a bad posture within the measurement distance by theposition detecting unit 30 of the display mounting control system 40.

The move-to-up stage 1540 indicates that a state in which the posture ofthe user moves up and the user may indicate a state that the position ofthe face of the user moves up within the measurement distance by theposition detecting unit 30 of the display mounting control system 40.

The move-to-home stage 1550 indicates the movement to a home positionand indicates that the user is moved to maintain a correct posture bythe display mounting control system 40.

However, the state of the state diagram 1500 is not necessarily limitedto those described above.

According to the exemplary embodiment of the present invention, when theposture of the user is unstable in the unknown stage 1510, the statediagram 1500 may change the state to the user exist stage 1520.

When the user concentrates in the user exist stage 1520 to move theposture down, the state diagram 1500 changes the state to the badposture stage 1530.

It is determined to adjust the display upwardly or downwardly in the badposture stage 1530 so that the state diagram 1500 changes the state tothe move-to-up stage 1540.

When the position of the display moves in the move-to-up stage 1540 sothat the posture of the user is up, the state diagram 1500 is passed andeven though the position of the display is moved, when the posture ofthe user is down and unstable, the state diagram 1500 is failed tochange the state into the move-to-home stage 1550. Here, if it isfailed, the bad posture stage 1530 is determined again to adjust theposition of the display.

According to the exemplary embodiment of the present invention, thedisplay mounting control system 40 designs a customized training by thestate diagram 1500.

When the display 20 is lifted by the display mounting control device 10,the user may complain of discomfort at a specific height after theposture is induced for a while. This may be caused because a range ofmotion of the cervical spine is different for each user. Accordingly,the display mounting control system 40 may determine which posturechange is shown by the user at a height of a distance which moves thedisplay 30 and this may be confirmed by the move-to-up stage 1540 of thestate diagram 1500.

The display mounting control system 40 checks a ratio of the previouspass and failure (fail) in the bad posture stage 1530 in which thedisplay 20 needs to be lifted to determine to increase or decrease thedistance that moves the display 20.

The display mounting control device 10 may additionally include a buttonthat is pressed for a long time to reset the record for the customizedtraining, on a side surface.

According to the exemplary embodiment of the present invention, thedisplay mounting control system 40 acquires posture information duringthe display 20 used time and concentrated time data during the display20 used time and transmits the acquired data to the outside in awireless (Bluetooth) manner or a wired (USB or cable) manner.

Further, the display mounting control system 40 provides the feedback ofthe posture habit change to the user, predicts a musculoskeletal diseaseaccording to the posture habit to provide the predicted result to theuser, provides the feedback of the immersion pattern to the user, andprovides a concentration strengthening training according to theimmersion pattern.

By doing this, the display mounting control system 40 may obtain theeffects of reducing the industrial accident insurance premium of thecompany by predicting the musculoskeletal disease and enhancing theproductivity of the company by the concentration strengthening training.

According to still another exemplary embodiment of the presentinvention, the position detecting unit 30 may calculate a first regiondistance, a second region distance, and a third region distance from theposition detecting unit 30 on the basis of the acquired sensor value.When the position detecting unit is a TOF sensor, a distance value forevery pixel may be calculated by calculating the TOF sensor value andthe control unit 32 may determine a distance to a specific point (acenter point) of each region as a representative distance for everyregion. The control unit 32 may determine the state in which the firstregion distance>the third region distance>the second region distance asa normal posture stage. When the time differential value with respect toat least one of the first, second, and third region distances,specifically, the first region distance is negative, the control unit 32may be determined it as a “bad posture prestage”. In the case of the badposture prestage, the control unit 32 may transmit a warning message (awarning operation) to upwardly drive the monitor or upwardly drive themonitor a little bit and then downwardly drive the drive in its originalposition to the user.

Further, the third region distance is larger than the first regiondistance and the first region distance is smaller than the firstreference value, it is a bad state in which the user bents the neck andthe waist toward the monitor so that the control unit 32 determines thecurrent posture as a “first bad posture stage”. Here, the firstreference value may be determined in the range of 40 to 60 cm, which mayvary according to the usage environment. In this case, the control unit32 may quickly drive the motor to upwardly move the display to switchthe posture of the user to a desirable direction.

Further, even though the distance of the third region is larger than thefirst region distance, if the first region distance is larger than thefirst reference value, the control unit 32 may determine the currentstate as a “second bad posture stage”. This is because the distancebetween the display and the user (head) is long, but the neck is bent.Further, the distance of the second region is farther than any one ofthe first region distance or the third region distance, the control unit32 determines the current posture as a “bad posture prestage” andperforms the above-described warning operation.

According to the exemplary embodiment of the present invention, thewarning message notifies the user of the bad posture stage by anoperation of repeating an operation of lifting or lowering the display20 by the display mounting control device 10, an operation of turningon/off a warning light to provide a warning to the user, an operation ofdriving the driving motor 200 at a very high speed to move the displaymounting control device 10 at a high speed, and an operation ofproviding a warning sound. However, it is not necessarily limitedthereto and the warning message may be provided by an operation ofinforming the user of the bad posture state.

FIG. 17 includes diagrams showing a noise according to an operating timeof a display mounting device for posture correction.

(a) of FIG. 17 is a view illustrating a noise according to an operatingtime of a display mounting device for posture correction according tothe existing method. (b) of FIG. 17 is a view illustrating a noiseaccording to an operating time of a display mounting device for posturecorrection according to the exemplary embodiment of the presentinvention.

In the display mounting device for posture correction, the arm unit 30performs the linear motion by the operation of the driving motor 200 tobe stretched or extended so that the noise may be generated as thedriving motor 200 operates.

Referring to (a) of FIG. 17 , in the display mounting device for posturecorrection of the related art, when the motor does not operate, thenoise is not generated but when the operation of the motor is rapidlyperformed to adjust the length of the arm unit, a loud noise may begenerated. At this case, the generated noise may distract the user whouses the display mounting device for posture correction.

Human hearing is sensitive to the changes so that the noise generated bythe operation of the driving motor 200 of the display mounting device 10for posture correction may distract the user who uses the displaymounting device 10 for posture correction. The display mounting device10 for posture correction of the present invention may be implemented asfollows so as not to distract the user.

The display mounting device 10 for posture correction sets a maximumdriving speed of the rotational driving force of the driving motor 200according to the movement length that the arm unit 300 is stretched orextended and after gradually increasing the rotational driving force tothe maximum driving speed along the movement length that the arm unit300 is stretched or extended for a predetermined time, and thengradually decreases the rotational driving force.

Referring to (b) of FIG. 17 , in the display mounting device 10 forposture correction, the noise is not generated while the driving motor200 does not operate and the driving motor 200 is linearly driven toadjust the length of the arm unit 300 so as not to distract the user.

As an operation noise is proportional to a rotational speed of thedriving motor, the display mounting device 10 for posture correction mayminimize a distraction factor of the user by adjusting a rotationalspeed (RPM) according to the movement distance. Here, the rotationalspeed of the driving motor may be set by multiplying the stretcheddistance by a predetermined constant.

When the driving motor 200 operates, the speed of the display mountingdevice 10 for posture correction is linearly changed and as the speedrises to the maximum speed and then is lowered, an inflection point maybe formed as illustrated in (b) of FIG. 17 , but is not necessarilylimited thereto. Here, the inflection point is a maximum driving speedof the driving motor 200.

Specifically, unlike the related art that when the length of the armunit 300 is adjusted, a loud noise is generated during the high-speedoperation, the display mounting device 10 for posture correction adjuststhe rotational speed according to the movement distance of stretchingthe arm unit 300 and as the speed is gradually increased, the noisegenerated by the driving motor 20 is gradually increased and then thespeed is gradually reduced with respect to the inflection point tominimize the distraction element of the user.

The display mounting device 10 for posture correction may set a maximumdriving speed which causes a noise which does not distract the user andadjust the speed of the driving motor 200 according to the movementdistance with respect thereto. Here, the display mounting device 10 forposture correction may further consider the movement time and sets amaximum movement time until the arm unit 300 moves to be fixed tomaintain a target posture. Accordingly, the display mounting device 10for posture correction linearly drives the driving motor 200 such thatthe movement distance of the arm unit 300 does not exceed the maximumdriving speed within a predetermined movement time to maintain a targetposture.

Specifically, when the arm unit 300 moves by a predetermined distance,the display mounting device 10 for posture correction operates thedriving motor 200 to increase the speed by half the predetermineddistance and when the speed reaches to the maximum driving speed,operates the driving motor to reduce the speed of the driving motor byhalf the predetermined distance to stop the operation.

Accordingly, the display mounting device 10 for posture correctionincreases the usage convenience by controlling the stretching speed tobe gradually increased.

According to another exemplary embodiment of the present invention, thecontrol unit 32 classifies the state of the user into a normal state oran abnormal state (for example, a bad posture stage) and varies anacceleration of the driving motor according to the state of the user.

For example, the posture of the user is normal and a button (notillustrated) manipulating signal of the user for adjusting a height ofthe display 20 is input, the control unit 32 sets to increase the speedof the driving motor according to a 1-1-th acceleration and decrease thespeed the driving motor according to a 1-2-th acceleration. Here, themanipulating signal which is input by the user to adjust the height ofthe display 20 may be generated not only by a button, but also byadjusting a normal posture setting by the control unit 32.

When it is determined that the posture of the user is an abnormal state,that is, the posture of the user is in a bad posture stage, the controlunit 32 moves the display 20 to maintain the normal state. At this time,the control unit 32 is set to increase the speed of the driving motor200 at an acceleration which is lower than the 1-1-th acceleration anddecrease the speed of the driving motor 200 at an acceleration which islower than the 1-2-th acceleration. Further, in the example of FIG. 17 ,a gradient indicates an acceleration at which the display moves and amagnitude of the acceleration may vary according to the abnormal stagedegree of the user. For example, when the user's abnormal state is mild(for example, it can be determined according to an error index), theacceleration in the increase section can be made relatively small andwhen the abnormal state is severe, the acceleration may be relativelyincreased by the increase section.

Even though it has been described above that all components of theexemplary embodiment of the present invention are combined as onecomponent or operate to be combined, the present invention is notlimited to the exemplary embodiment. In other words, one or morecomponents may be selectively combined to be operated within a scope ofthe present invention.
